This module has been created for developers who are willing to make themes/extensions for Google Chrome that modifies the default newtab page chome://newtab. You can add your custom styling/JS to tweak the newtab page. e.g. hiding the most visited tiles, decorating the search bar, replacing the Google logo with whatever you like and so on.

There was a lot of modules for tweaking the newtab page and all of them stopped working up until several months ago because of the change of chrome://newtab behaviour. However, I tried to find a way to bypass that and came up with this module that will let to you customize the default newtab page like before.
You can use this as an extension right now using Chrome's extension developer mode.
